Anything in this world that has mass and takes up space
What is matter
100
Define the term "kinetic"
Movement
100
Another term for "freezing"
What is solidification
100
What is the formula for calculating density?
density = mass/volume
100
This fluid has a density of 1g/mL
What is water
200
What are the three forms of matter?
Solid, liquid, and gas
200
The energy that particles possess that allows them to move
What is kinetic energy
200
A change in state from gas to liquid form
What is condensation?
200
Define the term density
The mass of a substance in a given space. OR how closely packed together particles are.

When is Ms. Montgomery's birthday?
October 31st
300
What are the two forms of matter that make up fluids?
Liquids and Gases
300
The average kinetic energy of a substance
What is temperature
300
What happens to the movement of particles when they gain more energy?
The particles move faster and further apart
300
List the states of matter from most dense to least dense
Solid, liquid, gas

Chocolate
400
Name one thing that is not matter
Energy
400
This state of matter has a definite volume, but no definite shape
What is a liquid
400
Draw what the particles look like during the process of evaporation
Particles closer together and moving slower in liquid state. Particles farther apart and moving faster in gaseous state.

An 8g crumpled up piece of tin foil is placed in 20mL of water. The water now reads 23mL. What is the density of the tin foil?
d=m/v
8g/3mL = 2.7g/mL
400
True or False: As fossil fuels are burned, carbon dioxide (CO2) is released into the atmosphere, which allows more heat to escape from Earth
FALSE: more carbon dioxide means more heat is TRAPPED in Earth's atmosphere
500
List the three states of matter in order from particles containing the most amount of energy to particles containing the least amount of energy
Gas, Liquid, Solid
500
True or False: there is empty space between all particles
True! This is the second rule of the kinetic molecular theory
500
Define deposition
The change in state from a gas directly to a solid
500
Given the following densities:
Water: 1000 g/L
Mayonnaise: 910 g/L
Corn oil: 922 g/L
Diesel: 800 g/L
Draw what it would look like if all of these fluids were mixed together:
They would form layers in the following order (top to bottom):
Diesel
Mayonnaise
Corn oil
Water
